Switch multicast distribution system to round-robin mode
Send one packet from each eraseblock in turn, rather than all packets
for one eraseblock together. This means that bursts of loss are evenly
spread between blocks. It also makes the client side a bit more complex
if you can't assume that there's anywhere except the flash to store its
intermediate data.
